POLISH-BOD SUPPORT.

Application filed-October .6, 1925. Serial No. 60,926.

To all who mat may concern:

Be it known that I, LEONARD Loor, a citizen of the United States,residing at Tulsa, in the county of Tulsa and State of Oklahoma, haveinvented a new and useful Polish-Rod Support, of which the following isa specification. 1

The present invention relates to a connectconnecting a polish rod to apumpbeam,

novel means being provided for adjusting the polish rod with respect tothe valve members that operate below the polish red.

A further object of the invention is to provide a device of thischaracter which will permit of an adjustment of the polish rod,eliminating the necessity of employing beam hangers which often allowthe polish rod to drop, necessitating the loss of time to recover thesame.

A still further object of the invention is the provision of meanswhereby an adjustment may be readily and easily made, eliminating anypossibility of the polish rod With the foregoing and other objects inview which will app-ear as the description proceeds, the inventionresides in the combination and arrangement of parts and in the detailsof construction hereinafter described and claimed, it being understoodthat changes in the precise embodiment of the invention hereindisclosed, may be made within the scope of what is claimed, withoutdeparting from the spirit of the invention.

Referring to the drawings: Figure 1 is an elevatlonal view 1llustrat mga connecting member constructed in accordance with the invention andillustrat-- ing one end of a pump beam.

Figure 2 is a perspective view of the adjusting member.

Figure 3 is a sectional view taken on line 33 of Figure 1.

Figure 4 is a sectional view taken on line 4-4 of Figure 3.

Figure 5 is a sectional view taken on line 55 of Figure 3.

Figure 6 is a sectional view taken on line 66 of Figure 3.

Referring to the drawings in detail, the reference character 5 indicatesa pump beam which is of the usual construction and is provided withhearing members 6 formed mg member especially designed for use in withcut out portions to accommodate the cross arm 'l" forming a part of theconnectmg device.

The cross arm 7 is formed at the upper the head 11 of the reducedportion 8. This connecting member includes an elongated body portionhaving its front and rear wallsout away defining guide members 12between which the 'adjusting member to be hereinafter more fullydescribed, moves.

Positioned at a point substantially intermediate the ends of the bodyportion are the bearing blocks 13 which are held together by means ofbolts 14, the bearing blocks 13 being secured in position on the bodyportion in any suitable and well known manner. The 'reterence character15 indicates a feed sleeve which is provided with a peripheral groovedefining spaced flanges 16 that operate on opposite sides of the bearingblocks 13 to permit of rotary movement of the sleeve 15 but insureagainst movement of the feed sleeve 15 longitudinally of the bodyportion.

The lower portion of the feed sleeve 15 is threaded to receive the upperthreaded end of the tubular member 17, while the lower end of thetubular member 17 is threaded in the head 18 of the sleeve 19 which headrests on the base 20 of. the elongated body portion to insure againstthe elements supported by the head 18 moving longitudinally of the bodyportion. At the lower end of the sleeve 19 are flattened portions 21constructed to receive a suitable wrench whereby the rotary movementwill be imparted to the sleeve 19, tubular member 17 and feed sleeve 15.

Movable between the guide members 12 is a supporting screw 22 that movesthrough the feed sleeve 15 as clearly shown by Figure 3 of the drawings.In order that the screw 22 will be held against rotary movement, a guideblock 23 is provided which is of a width to operate between the guidemembers 12, the guide block 23 being however secured to the upper end ofthe screw 22.

Formed in the lower end of the feed screw 22 is a threaded socket 24Lthat accommodates the threaded extremity 25 ot the polish rod 26 so thatthe polish rod may be connected to the screw 22 to move verticallytherewith. 1

From the foregoing it will be obvious that should it be desired toadjust the polish rod 26, it is only necessary to place a wrenchon theflattened portion of the sleeve 19, rotat ing the tubular member 17 andfeed sleeve 15, with the result that the feed screw 22 is movedlongitudinally of the elongated body portion, thereby eliminating the necessity of removing the polish rod from its connecting member in orderto make the adjustment.

I claim:

1. In a device of the character described, a body portion, a feed sleevemounted within the body portion and adapted to rotate wit-h respectthereto, a sleeve having a head mounted for rotary movement at the baseof the body portion, a tubular member connecting the sleeves, a screwmovable through the feed sleeve, means for connecting the polish rod tothe screw, and said screw adapted to operate to move the polish rodlongitudinally of the body portion.

2. Ina device of the character described, a body portion comprisingspaced guided members, bearing blocks supported between the guidemembers and held against movement, a separable base on the guidemembers, said separable base embodying asuphaving a threaded portionadapted to be adjusted through the bearing blocks, and means for raisingand lowering the body portion.

In testimony that I- claim the foregoing as my own, I have heretoaffixed my signature.

LEONARD LOOP.
